Aging effect in ceramic superconductors.

A three-dimensional lattice of the Josephson junctions with a finite self-conductance is employed to model ceramic superconductors. By using Monte Carlo simulations it is shown that the aging disappears in the strong screening limit. In the weak screening regime, aging is present even at low temperatures. For intermediate values of the self-inductance, aging occurs in an intermediate temperatur...

Ballistic Performance of Hybrid Armor with Ceramic Inserts and Polymeric Matrix for Different Threat Levels (TECHNICAL NOTE)

  Ceramic materials due to their high compressive strength and hardness have been one of prime candidates in armor design in particular when high level threads (impact velocity above 600m/s) are involved. The aim of this work is to investigate ballistic impact resistance potential for a target plate with novel ceramic inserts as against ceramic tiles. Two size 98% alumina (AL2O3) base ceramic i...

Micro-stereolithography of polymeric and ceramic microstructures

Ž . Micro-stereolithography mSL is a novel micro-manufacturing process which builds the truly 3D microstructures by solidifying the liquid monomer in a layer by layer fashion. In this work, an advanced mSL apparatus is designed and developed which includes an Ar laser, the beam delivery system, computer-controlled precision x–y–z stages and CAD design tool, and in situ process monitoring system...

Tubular Ceramic Foam Via Polymeric Sponge Method

Tubular ceramic foams were prepared by using natural clay as starting material and 120 ppi polyurethane foam as template via polymeric sponge method. Samples were sintered with different temperatures from 1200°C to 1280°C. The result shows that 1250°C is the ideal sintering temperature where the highest compressive strength of 1.980MPa at 47.31% porosity is obtained. The highest value in compre...

Quenching Effect on the Pb-Substituted Bi-Based Bulk Ceramic Superconductors

The effect of cooling process for the synthesis and the superconductivity properties of Pb-substituted Bi-based materials, has been investigated. The preparation condition for the formation of (2,2,2,3) phase has been examined. The influence of thermal condition of the synthesis and quenching on the critical temperature and the content of 110K phase was investigated. Results of the ac-susceptib...
